An International, Multicenter, Randomized, Double-blind, Placebo-controlled, Phase 3 Study to Determine the Efficacy and Safety of SYR-322 When Used in Subjects With Type 2 Diabetes

The purpose of the study is to determine the efficacy of alogliptin compared to placebo when given alone or as add-on therapy to metformin or add-on to pioglitazone (with or without metformin).

本研究旨在评估阿格列汀（alogliptin）单药治疗、作为二甲双胍的附加联合疗法，或与吡格列酮联用（此时吡格列酮可单独使用或与二甲双胍联用）时，相较于安慰剂的临床疗效。
